区域规则聚（3-己基硒烯）（P3HS）与氧化锌（ZnO）结合使用，制成光响应高达740 nm的混合聚合物-金属氧化物太阳能电池。以P3HS和二乙基锌为反应前驱体，在潮湿的气氛中从普通溶剂中铸造P3HS，然后在薄膜中转化为ZnO，制备了紧密混合的ZnO:P3HS层。采用光诱导吸收光谱法对P3HS与ZnO在光照下发生的电子转移反应进行了表征。对ZnO:P3HS太阳能电池的组成、层厚和转换温度进行了优化，使其在模拟太阳光照下的最终功率转换效率达到0.4%。其性能主要受短路电流低的限制。通过对光谱分辨外量子效率与光吸收的比较，我们发现P3HS丰富的半晶相对光电流的贡献可以忽略不计，而光电流主要是由P3HS中稀缺的非晶区所主导的。
Regioregular poly(3-hexylselenophene) (P3HS) is used in combination with zinc oxide (ZnO) to make hybrid polymer–metal oxide solar cells with a photoresponse up to 740 nm. Intimately mixed ZnO:P3HS layers were prepared by casting P3HS and diethylzinc as a reactive precursor from a common solvent in a moist atmosphere, followed by conversion to ZnO in the film. Photoinduced absorption spectroscopy was used to identify the electron transfer reaction occurring from P3HS to ZnO under illumination. The performance of ZnO:P3HS solar cells was optimized for composition, layer thickness, and conversion temperature to a final power conversion efficiency of 0.4% in simulated solar light. The performance is primarily limited by a low short-circuit current. By comparing the spectrally resolved external quantum efficiency with the optical absorption, we find that the abundant semicrystalline phase of P3HS gives a negligible contribution to the photocurrent, which is dominated by the scarce amorphous P3HS regions in di...
